This
eighteen-carat gold Mont Blanc pen contains a receiver to enable 007 to track
the bug in the Fabergé egg. The barrel also holds a portion of acid capable
of dissolving metal. Bond uses this to escape from his imprisonment in Khan's
palace by burning through metal bars on the window. The pen also contains an
earpiece which works in conjunction with the bug in the Fabergé egg,
allowing 007 to listen in on conversations between
Orlov and Khan.
